From mboxrd@z Thu Jan 1 00:00:00 1970 From: John Keller Date: Fri, 02 Feb 2007 20:54:12 +0000 Subject: [PATCH 1/1] - Altix: more ACPI PRT support Message-Id: <20070202205412.14367.60290.sendpatchset@attica.americas.sgi.com> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: linux-acpi@vger.kernel.org Cc: ayoung@sgi.com, linux-ia64@vger.kernel.org, linux-kernel@vger.kernel.org, John Keller The SN Altix platform does not conform to the IOSAPIC IRQ routing model. Add code in acpi_unregister_gsi() to check if (acpi_irq_model = ACPI_IRQ_MODEL_PLATFORM) and return. Signed-off-by: John Keller --- Due to an oversight, this code was not added previously when similar code was added to acpi_register_gsi(). http://marc.theaimsgroup.com/?l=linux-acpi&m6680983430121&w=2 arch/ia64/kernel/acpi.c | 3 +++ 1 file changed, 3 insertions(+) Index: linux-2.6/arch/ia64/kernel/acpi.c =================================--- linux-2.6.orig/arch/ia64/kernel/acpi.c 2007-02-02 14:44:31.000000000 -0600 +++ linux-2.6/arch/ia64/kernel/acpi.c 2007-02-02 14:47:44.658143727 -0600 @@ -609,6 +609,9 @@ EXPORT_SYMBOL(acpi_register_gsi); void acpi_unregister_gsi(u32 gsi) { + if (acpi_irq_model = ACPI_IRQ_MODEL_PLATFORM) + return; + iosapic_unregister_intr(gsi); }
